Claims.

This invention relates to means for attaching pocket engaging clips topen caps, pencils, or other hollowmembers, commonly carried in upright position ina pocket, and has for its object the provision of an improved attaching means of this character which can be easily and quickly applied to an article, is particularly adapted for use in the new style pen holders and mechanical pencils in which the rear ends thereof are gradually rounded in more or less tapered form, and, more case of a pen holder cap, provides a pen-receiving chamber, the closed end of which is sealed against the escape of ink or the admis-. sion of air around the clip anchoring means. i

The invention isfully described in the following specification, and three embodiments thereof 20. fountain pen cap,

illustrated in the accompanying drawing, in

I

Referring to the draw1ng,.and particularly to Figs. 1 to 5, 10 designates an article of tubular form to which a clip 11 is to be attached, and which article, in its present embodiment, constitutes a cap of the type commonly used on fountain pens.

The bore of the article 10 is reduced near its closed end to form a shoulder 12, preferably annular in form or extending completely around the interior of the bore; This shoulder,.at one side of the bore, is notched inwardly a distance toward the closed end of the article to provide a key-way 13, the bottom of which is substantially in a plane with or forms an extension of the inner wall surface of the large bore of the article.

An opening 14 is provided through the side wall' of the article 10 at the same side as the key-way 13 in longitudinal alignment therewith and spaced a short distance from the shoulder 12.

The clip 11, which, in the present instance, is of the lever type, has its carrying spring 15 projected through the opening 14 and then extending fiat along the inner side of thearticle 10 lengthwise thereof toward its closed end with its free end portion seating in the key-way 13, so that the side wails of the opening 14 and of the key-way cooperate to prevent any lateral movement of the spring angularly of the article axis.

The clip-spring 15 is securely anchored in the article 10, in the present instance, by-means of a disk or washer 16 and a cylindrical lining member 1'7, both of sizes to fit snugly within the large bore of the member 10 and the lining member being of a length to extend from the shoulder 12 to a point beyond the opening 14, so that the opening is closed thereby, and also so that the outer end of the member 17 may serve as a shoulder against which the pen-carrying nib of a fountain pen may seat, as well understood in the art. The side of the member 17, which engages the clipspring 15, is chamfered for a distance necessary to permit it to pass over the coacting portion of the spring, as shown in Figs. 1, 4 and 5. Interposed between the washer 16 and lining 17 is a 86 gasket disk 18, which is of stiff rubber, or other suitable material, capable of serving as a sealing means between the members 16 and 17, and of closing the opening 19 through the washer 16, and at the same time being capable of perforation by a sharp instrument for the purpose hereinafter described.

In assembling the spring-anchoring parts, the washer 16, which is preferably of metal or other suitable stiff material, is first forced into the bore of the article 10 over the spring 15, and in abutment against the shoulder 12. The gasket member 18 is then placed in the bore against the washer 16 to close the opening therethrough, and the lining member 17 then forced into: the bore with its inner end pressed against the gasket 18 to closely hold it to the washer 16 with its chamfered side in holding engagement with the registering portion of the spring 15. With this arrangement, the chamber at the open or penpoint receiving end of the article 10, if it be a fountain pen cap, is hermetically sealed both against the escape of liquid therefrom or the admission of air thereto through-the opening 14 and along the spring end. When it is desired to remove the spring-attaching members to permit replacement of a broken clip or spring, the gasket 18'is perforated by a sharp instrument, which latter may then be passed through the opening 19 0f the washer 16 and hooked around theinner side of the washer to permit it, together with the gasket 18 and lining member 17, to be withdrawn from the cap, after which the spring 15 may be removed and a new one, with clip attached, substituted therefor, and the members 16 and 1'7 with a new gasket member 18 then replaced to secure the spring in position.

In the form shown in Fig. 6, which is intended more particularly for use in connection with mechanical pencils, or other articles, wherein it is not necessary to seal the interior of the member from the atmosphere, the washer 16 and gasket 18, shown in Fig. 1, are omitted, and the lining member may be extended to the open end of the member and may also be of metal, whereas, in the form shown in Fig. 1, it is preferable to make such member of vulcanized rubber, or similar material.

In the form shown in Fig. 6, the bore of the hollow article, which is designated 20, is of the same size throughout its length and a lining member 21' is forced therein to have side engagement at its inner end portion with the longitudinal extending portion of the spring 15. The inner end of the lining 21 may be formed in one side thereof with a longitudinally extending depressed portion 22 to fit over the registering portion of the spring 15, or, if the lining 21 is of a yielding material, such as thin brass tubing, it may be forced into the article 20 in holding engagement with the spring, and during such action shape itself to fit around the spring.

In this form of the invention, the spring is firmly held to the side of the inner side wall'of the article 20 by the binding action of the lining member 21, and the engagement of the end of the spring in the registering key-way cooperates with the side walls of the opening 23 in the article wall through which the spring extends.

The form of spring attaching means shown in Fig. 1, or that shown in Fig. 6, is adapted for use in connection with the new style cap or tubular article shown in Fig. 8. The only difference in the cap or article construction in Fig. 8 is that the wall of the inner reduced end portion of the article bore is rounded to conform to the gradually rounded taper-like form of the article end, and the key-seat 23, instead of being straight longitudinally of the article, is curved to follow the curvature of the article wall in which disposed. Y I r I It is apparent that in either form of the invention the clip-spring is securely anchored in position within the article in such a manner as to hold the clip against any lateral twistingaction relative to the article, and that in the form of the invention illustrated in Fig. 1, the penpoint receiving chamber of the cap member is hermetically sealed against the escape of liquid therefrom or the admission of air thereto through the opening 14 and along the side of the spring. I wish it understood that my invention is not limited to any construction, arrangement or form of the parts, as it is capable of various modifica tions and changes without departing from the spirit of the claims. 7
